Three years into its product cycle, the fifth generation of the LS, flagship of the Lexus range, has received its first update which, besides cosmetic changes, see the introduction of Lexus Teammate advanced driver assist technologies.
Towards autonomous motoring
Lexus Teammate is another step towards autonomous motoring and is based on the Mobility Teammate Concept. The technology has five characteristics: Perceptive, Intelligent, Interactive, Reliable, and Upgradable. It can seamlessly incorporate future software updates that allow functions to be continually added and performance to be continually enhanced to meet customer needs.
Advanced Drive performs peripheral recognition, estimates vehicle position, calculates vehicle lane and position, adjusts speed, and conducts other tasks on motor-vehicle-only roadways for safe driving support all the way to the roadway exit.
Advanced Park uses cameras and ultrasonic sensors to provides parking assist through driver operation of intuitive controls. It automatically controls acceleration, braking, and gear changes. It not only provides people with safety as a matter of course but also with a parking experience that gives them a sense of precision and security.
Through integrated cameras and ultrasonic sensors, the latest advanced parking assist technologies support the driver in recognition, judgment, and operation. Besides support of all operations – steering, acceleration, braking, and gear changes – the bird’s-eye view display also shows the ideal steering wheel positions for a safe and secure parking experience.
High-tech lighting
The new LS also features BladeScan AHS (Adaptive High-beam System), which debuted as a world’s first on the partially redesigned Lexus RX in 2019. In this system, LED-sourced light shines onto a blade mirror spinning at high speed and is transferred to a lens to illuminate the road ahead. While the light does not appear to be moving due to a residual image effect, BladeScan AHS precisely controls light distribution by synchronizing the rotation of the blade mirror and switching the LED headlamps on and off.
Because the effect of the high beam can be expanded in a more-natural manner, the system illuminates areas that might be difficult to see with conventional high-beam systems, such as the shoulder of the road. It also allows the driver to recognize pedestrians and road signs much earlier, without impeding the visibility of drivers of oncoming or preceding vehicles.
Other technical changes include increased battery assist during acceleration at often-used driving speeds with more quietness in the hybrid variant. The petrol engine of the LS500 has been retuned for improved initial engine torque at often-used driving speeds to offer greater acceleration response. Shift timing has also been recalibrated to enhance smoothness and provide a wider acceleration range for each gear so there are less frequent downshifts.
All variants of the new LS have undergone Active Noise Control and Engine Sound Enhancement tuning for improved quietness, a key aspect of Lexus since the first model was launched in 1989.
A newly developed Adaptive Variable Suspension solenoid reduces damping force, while the vertical spring rate (stiffness) of the run-flat tyres and the rigidity of the stabilizer bars provide optimized performance. Also, the orifice inside the engine mounts has been changed so as to alter damping characteristics, resulting in a reduction in vibrations transmitted into the cabin.
Interior changes
“Hospitality’ has been a feature of Lexus models right from the start and greatest efforts are made to provide occupants with the best comfort to enjoy each journey. For the latest LS, the interior presents various expressions amid the transition of time. Ornamentation is available for the first time in ‘Nishijin & Haku’ (with ‘haku’ being the Japanese word for ‘metal leaf’). By expressing the existence of a ‘path of moonlight on the sea’ formed by the sparkles of light on moonlit waves through the silver threads of Nishijin brocade and the sparkle of platinum leaf, Lexus has aimed to provide the comfortable and relaxing atmosphere that would be expected of a true brand flagship.
Besides a digital rearview mirror for the driver, the multimedia system features a new touch display and is compatible with SmartDeviceLink, Apple CarPlay, and Android Auto. Convenience has been greatly enhanced by the ability to control the display screen and audio functions by using an iPhone and Android smartphone linked to the 12.3-inch touch-operated wide display.
The seat coverings feature deeper stitch points, and the underlying seat pads have low-resilience urethane. Vibration absorption and soft seating contribute to even more enhanced comfort.
New paint technology
Gin-ei Luster – a new paint technology and colour providing deep shadows and robust highlights is used on the bodywork of the LS. This comes from much effort spent in the development of silver paint finishes. The new colour is applied using the Sonic Method, which condenses the paint volume of paint containing radiant material (aluminium flakes). The new colour also employs the latest paint technology in which an aluminium evaporation coating is spread over surfaces in high density.
With a smooth, mirror-like texture that is all but absent of a granular touch, the most-notable characteristics of Gin-ei are the beautiful sparkles of light found in its highlights and the sense of depth created by its deep shadows. It reacts to the even slight amounts of surrounding light and that transforms in concert with the transition of time and with changes in the environment to display a variety of expressions.
Providing a safer mobility experience
“The LS, as a flagship, has constantly pursued innovation and has provided new technologies and value for its customers,” said Lexus International President, Koji Sato. “In developing the new LS, we furthered the evolution of the exceptional quietness and comfort that has been a steadfast constant since the model’s first generation, and, by employing the advanced driving assist technologies of Lexus Teammate, we aimed for a mobility experience that is much safer and more secured than before.”
The new model will go on sale in Japan towards the end of 2020, so sales in overseas markets like Malaysia would only start in 2021.
